MACHINE FOR SHAPING OR FORMING CORES FOR THE BOW-SOCKETS OF CARRIAGE-TOPS.

SPECIFICATION forming part of Letters Patent No. 453,384, dated June 2, 1891.

Application filed November 4, 1890. Serial No. 370,298. (No model.) Patented in Canada January 9, 1890, No. 33,362.

v ented in Canada under No. 33,362, dated Jannary 9, 1890,) fication.

This invention relates to machines for shape ing or forming cores for the bow-sockets of carriage-tops; and it has for its object to conof which the following is a specistruct a machine of this class by means of which such cores or filling, which are usually made of wood, may be easily and quickly compressed to the desired shape.

WVith these ends in view my invention consists in a pair of compressing or shaping rolls suitably mounted, a pusher for automatically feeding the blanks to the said rolls, a saw by means of which a kerf may be cut inthe core or filling, and mechanism for operating the several parts in unison, all as will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a top plan view of a machine constructed in accordance with my invention. Fig. 2 is a sectional elevation of the same, taken on the line 2 2 in Fig. 1. Fig. 3 is an end elevation. Fig. 4 is a side elevation. Fig. 5 isa perspective view showing one of the blank strips ready to be compressed by the machine. Fig. 6 is a perspective view of one of the cores, which is the product of the machine.

Like numerals of reference indicate like parts in all the figures.

1 designates a base or platform, having uprights 2 2, which are provided with boxes or bearings for the shafts 3 and 4, one of which is j ournaled directly above the other, and which are geared together by car-wheels 5 6, which are driven by a belt-pulley 7 upon the shaft 3.

8 and 9 are rollers, which are mounted upon the shafts 3 and 4, respectively. The said rollers have interrupted peripheries, and they are provided with tapering grooves 8 and 9, registering with each other, the rollers being outer end of the table.

journal'ed so that the interrupted sections shall face each other at each rotation. The groove 8 in the roller Sis provided with a rib 8", for the purpose of impressing the corestrip with a groove, (shown in Fig. 6 at 8,) which shall serve to receive the raised inside seam at the joining of the bow-socket material.

10 designates a table, upon which the blank is placed to be fed between the rollers 8 and 9, and said table is provided at its inner end with feed-rollers 11 11 mounted between the guide-walls 12. A

13 is a pusher, mounted to slide upon the Said pusher is operated by means of rods 1% jointed at 15 and terminating at their upper ends in hooks 15, which are adapted to be engaged by a bar 16, which is secured across the interrupted face of the roller 8, projecting on each side of the latter, so as to engage the hooks 15 at each rotation of the roller, and commence to draw the pusher 13 in a forward direction when the interrupted faces of the rollers are par allel, so as to feed the strips or blanks of wood to the rollers. The pusher 13 is retracted, on the release-of the hooks 15 from the crossbar 16, by means of a suitably-arranged retracted spring 1S. hen the strips or blanks, which are designated by 35, are passing between the rollers, the groovcs in said rollers serve to.crush or compress the strips or blanks sufficiently to round the opposite sides of the same. A strip or blank is fed ateach rotation of the rollers, the periphery of the rollers and the strips being of approximately the same length.

Suitably pivoted to the table are jaws 19 19, the inner ends of which are provided with rollers 20, which are peripherally grooved so as to round off the lateral sides of the strips or blanks before the latter are engaged by the compression-rollers 8 and 9, in advance of which the said rollers 20 are located. latter are forced in the direction of each other by the action of a spring 21, which is arranged to spread the opposite ends of the jaws 19, said spring being curved or bow-shaped, as will be seen in Figs. 2 and 4 of the drawings.

22 designates a bent rod, which is suitably The arranged to limit the spread of the jaws by the spring 21.

\Vhen it is desired that the shaped strip or core shall be longitudinally slit for the purpose of passing a rivet in the bow-socket, the slitting is effected by means of a horizontallyarranged circular saw 23, which is mounted on an arbor 24, having a bent pulley 27, and journaled vertically in a frame 25, which is arranged to reciprocate in a stand 26, which is secured in an upright position to the base 1 of the machine. The frame 25 is provided with a projection 28, adapted to be engaged by a semicircularly-bent cam-bar 29, the ends of which are suitably secured to the lower cog-wheel 5. When the latter revolves it will engage the projection 28 of the frame 25, pushing the latter in one direction to cause the circular saw 23 to engage the blank as the latter leaves the shaping-rolls, thus forming therein the slit 0r kerf 31. \Vhen the cam 29 passes out of engagement with the projection 28 of the frame 25, the latter is restored to its normal position by means of suitablyarranged springs 30.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood.

The blanks which are fed to the machine consist simply of tapering strips of wood,

which have been previously sawed to the proper shape and dimensions, substantially as shown in Fig. 1 of the drawings. \Vhen the compression-rollers rotate, the cross-bar 16 will engage the hooks at the ends of the rods 15, by means of which the pusher 13 is forced in a forward direction, causing the blank strip which has been previously placed in position upon the table to be fed forward between the feed-rollers 11 and the peripherally-grooved rollers 20, which serve to round off the lateral sides of the blank. The latter is then engaged by the compression-rollers, by frictional contact with which it is carried through the machine. In the meantime the cam 29 engages the projection 28 of the sawcarrying frame, which latter is forced laterally to such a position that the saw 23 shall engage the blank as it issues from the machine and forms the slit 31 therein. At the proper time the cam 29 passes out of engagement with the projection 28, and the saw-carrying frame is restored by means of the springs 30.

Vhile this operation is taking place, the attendant places the next blank in position upon the table ready to be fed forward by thisI pusher 13 on the next rotation of the r0 .s.

The machine, as will be seen from the foregoing, is very simple in construction, and it will form the filling-cores or bow-sockets very quickly, compactly, and accurately.

Having described myinvention, I claim- 1. The combination of suitably-grooved shaping-rolls geared together and having interrupted peripheries, a cross -bar secured across the interrupted face of one of the rolls, a longitudinally-reelprocating pusher, hookrods-adapted to connect the latter with the said cross-bar, and a retracting-spring, all arranged and operating substantially as set forth.

2. The combination of suitably-grooved shaping or compressing rolls, a reciprocating pusher adapted to feed the blank between the said rolls, peripherally-grooved shaping rolls mounted horizontally in suitable jaws in advance of the compressing-rolls, and a spring arranged to force the said horizontallyarranged shaping-rolls in the direction of each other, substantially as and for the purpose set forth.

3. The combination of the compressingrolls, having suitable grooves, the shapingrolls arranged in advance of said compressing-rolls, means for forcing the said shapingrolls in the direction of each other, the feedrolls journaled between suitable guide-walls, and the longitudinally-reciprocating pusher adapted to be operated automatically by the rotation of the compressing-rolls, substantially as set forth.

4. The combination, with the compressingrolls, having suitable grooves, as herein described, of a laterally-reciprocating frame having bearings for a shaft or arbor carrying a saw adapted to form a longitudinal slit or groove in the blank as it issues from the compressing-rolls, substantially as herein set forth.
